Baryon-strangeness correlation (CBS) has been investigated with a multi-phase transport model (AMPT) in 197Au+197Au collisions at \sqrt{s_{\rm NN}} = 200 GeV. The centrality dependence of CBS is presented within the model, from partonic phase to hadronic matter. We find that the system still reserves partial predicted signatures of CBS after parton coalescence. But after hadronic rescattering, the predicted signatures will be obliterated completely. So it seems that both coalescence hadronization process and hadronic rescattering are responsible for the disappearance of the CBS signatures.
